Kojic acid Description 

Kojic acid, also known as kojic acid and citric acid, is an organic acid with antibacterial activity produced by aerobic fermentation of glucose by Aspergillus oryzae at 30-32 ° C. The molecular structure is γ-pyrone with a substituent. Among the γ-pyrone compounds present in nature, the well-known compounds are only kojic acid and maltol.


In 1907, Saito separated the crystals of kojic acid from rice koji. It was named by Yabuta in 1912 and its structure was determined in 1924. In 1953, Arnstela (surface fermentation) and 1971 Beitian Mufu (deep fermentation) using isotope tracing techniques to prove that kojic acid is formed by direct oxidation and dehydration of glucose without carbon frame fracture. Kojic acid is present in the song, it is something people eat, safe to use.


In recent years, a large number of patent documents have reported the use of kojic acid in cosmetics. Tyrosinase is a key enzyme in the production of melanin. Kojic acid can be deactivated by chelation with copper of tyrosinase, which is the basis of its whitening effect. Clinical and applied test results show that kojic acid has a strong inhibitory effect on melanin production in human skin, and it is safe, non-toxic and does not cause leukoplakia sequelae. Kojic acid is better formulated with other preparations (such as SOD, placenta extract, amino acids, sunscreens, and various plant extracts). Kojic acid is mainly used for skin whitening products, anti-aging products, sunscreen products, whitening facial cleansers and beauty cosmetics. Kojic acid has a certain antibacterial activity. Gram-negative bacteria are more sensitive to sodium kojate than gram-positive bacteria, while most other antibacterial substances are the opposite. The antibacterial activity of kojic acid is much lower than other antibacterial substances, and its antibacterial activity is bacteriostatic rather than bactericidal. Kojic acid is not effective against yeast, viruses and phages.
